Gardening in June

This morning BBBH planted more flowers along the fence.
Meanwhile, I was engaged in pulling weeds and thistles in the "secret garden." Funny thing, that. I worked for about an hour, accomplished about what I could have done in fifteen minutes just a few short years ago, and felt like I had been working for six hours. Would someone explain the 'theory of relativity' for me once again?
